Indeed. That's directly addressed in their definition of the rule:

> No feigning surprise isn’t a great name. When someone acts surprised when you don’t know something, it doesn’t matter whether they’re pretending to be surprised or actually surprised. The effect is the same: the next time you have a question, you’re more likely to keep your mouth shut. An accurate name for this rule would be no acting surprised when someone doesn’t know something, but it’s a mouthful, and at this point, the current name has stuck.
